VEHICLE-WHEEL.

Specification of Letters Patent.

Patented May '7, 1912.

Application filed October 17, 1910. Serial No. 587,411.

State of Kansas, have invented certain new and useful Improvements inVehicle-Wheels, of which the following is a specification.

This invention relates to new and useful improvements in vehicle wheelsand has relation particularly to that type known as resilient or springwheels'and has for its object to produce a wheel of this character whichwill combine all advantages obtained by the use of pneumatic tires.

Another object of the invention is to pro duce a wheel of thischaracter, which will be cheap in construction, durable, and eiiicientin operation.

The invention consists in the construction and combination of parts tobe more fully described in the specification, and pointed out in theclaim.

Referring to the accompanying drawings: Figure 1 is a side elevation,Fig. 2 is a side elevation, parts being partially broken away to showthe interior construction, Fig. 3 is a detail view showing the sectionthrough one of the sets of springs and guide blocks, Fig. 4 is atransverse section on line tt of Fig 3, Fig. 5 is a longitudinal sectionmade on line 5-5 of Fig. 3, Fig. 6 is a side elevation of the expandingcover clamping ring, Fig. 7 is a detail view of one of the guide blocks.

Referring now to the drawings the present wheel comprises inner andouter spaced rims 1 and 2, respectively, the first mentioned rim havingspokes 3 suitably secured thereto, the inner ends of which are suitablyattached to a central hub l. The

'outer rim 2 is provided with inwardly extending side flanges 5. Securedintermediate of these flanges 5 are blocks or guides 6, adapted toreceive the ends? of the curved. rods 8 and 9. It will be noted that theblocks 6 are formed in two parts 10 and 11, each part being providedwith a semicircular groove 12, and when the top part of the block 6 isplaced upon the lower part 10 an opening 13 is provided to receive theends 7 of the curved rods 8 and 9. The opening 13 formed by the parts 10and 11 of the block 6 is of suflicient diameter to allow the ends of thecurved rods 8 and 9 to freely slide therein. It will also be noted thatwhen the parts 10 and 11 of the block are assembled an inclined face 14.is provided. It will be noted that one of the flanges 5 of the outer rim2 is of suflicientlength so that the same extends downwardly, as at 15.

The inner rim 1 is provided with up wardly extending side flanges 16,and has suitably secured to its outer face, intermediate the sideflanges 16 a block 17, said block having inclined faces. 18. The block17 is further provided with a forked opening 19 adapted to receive theinner ends of the curved rods 8 and 9. The curved rod 8 is provided witha bifurcated end 20 and the curved rod 9 is provided with an opening 21and adapted to fit within the bifurcated end 20 of the rod 8. The rod 8is likewise provided with openings 22 to register with the opening 21 ofthe rod 9, and when the rods are in this position they are placed Withinthe forked opening 19 of the block 17 and the bolt 23 is passed throughthe forked end of the block 17, and through the registered openings 21and 22 of the rod 8 and 9, respectively, thereby forming a pivotalconnection at the forked opening of the block 17. Loosely surroundingthe curved rods 8 and 9 are coil springs 24 and 25, the free ends ofwhich are adapted to rest against the inclined faces of the blocks 17and 6. The openings 13 of the blocks 6 are slightly curved, in crosssection, to accommodate the curvature of the ends 7 of the rods 8 and 9,thereby allowing free slidable action at these points.

As before stated one of the flanges 5 of the outer rim 2 extends belowthe edge of the opposite flange thereby forming a cover 26, for one sideof the wheel. Attached near the edge of one of the flanges 5 is aremovable circular plate 27, said plate being rigidly secured to theflange by suit-able fastening means, screw threaded bolts beingpreferable. From this construction it will be readily seen that theinner and outer rims will have a telescopic act-ion when the wheelpasses over obstructions, thereby allowing the springs, and theirconnections to relieve the jar incident to such action.

The numerals 31 designate suitable cover- These covers will exclude dustand- If desired a covering of leather 32 or othermaterial may be placedaround the outer rim 2, said covering being adapted to pass around theside flanges 5 and into a groove 33 formed in said flanges, and adaptedto be retained therein by means of an expanding ring 34. The expandingring 34; is of the usual construction, and comprises the down Wardlyextending lugs 35, said lugs having screw threaded openings therein anda screw threaded bolt 86 adapted to be operated to expand or contractthe ring 34.

WVhen it is desired to gain access to the inv terior construction of thewheel it is only necessary that the covering 27 be removed, thusobviating the necessity of disassembling the entire wheel.

That is claimed is:

A spring wheel comprising inner and outer spaced rims, the inner rimcarrying forked blocks provided with inclined faces, the outer rim beingprovided with spaced blocks and having curved openings formedtherethrough, the opposing faces of each being inclined, curved rodshaving pivotal connections with the blocks carried by the inner rim, andtheir free ends adapted to pass through the curved openings formed inthe spaced blocks carried by the outer rim, and coil springs surroundingthe curved rods, and having their terminals resting against the opposinginclined faces of the block carried by the inner rim and the inclinedfaces of the blocks of the outer rim.

In testimony whereof I aflix my signature, 1

in the presence of two witnesses.
